What oil boiler installation covers

A complete installation or like-for-like replacement, delivered with a focus on safety, performance and straightforward communication.

  • Site survey of the existing boiler, flue, oil supply and heating controls

When this service is the right fit

Oil boiler installation is most relevant if you:

  • Live in a property off the mains gas grid
  • Have an older, unreliable oil boiler or frequent breakdowns
  • Want improved efficiency, better temperature control or quieter operation
  • Are renovating and need the heating system brought up to date
  • Need a compliant replacement in a rented property

How the installation is delivered

Work usually starts with a practical assessment so the boiler specification matches the heating demand and existing system layout. Installation includes isolating the oil supply, making safe connections to heating and hot water, and setting up controls so the system runs efficiently. Before sign-off, the boiler is commissioned, safety-checked, and tested across heating and hot water to confirm stable operation.

After installation: handover and ongoing value

You will be shown how to use the programmer and thermostats, and what to monitor on the boiler. Keeping the boiler serviced annually helps maintain efficiency and reliability, and supports manufacturer warranty terms. If you are upgrading controls or making changes later, settings can be reviewed to keep comfort high and running costs under control.

Frequently Asked Questions

How long does an oil boiler installation usually take?
Many straightforward replacements can be completed in 1 to 2 days, but timings vary with flue changes, pipework alterations and access. You will be advised on the likely duration once the site survey is done.
Can you replace my oil boiler without changing the rest of the system?
Often yes, especially for like-for-like swaps where the pipework and controls are in good condition. If the system is sludged, undersized or poorly controlled, improvements may be recommended to protect the new boiler.
Will the installation meet Building Regulations and certification requirements?
Yes, the installation should be completed to the relevant standards and notified where required. You should receive the appropriate commissioning records and compliance paperwork for your property files.
Do I need to upgrade my heating controls at the same time?
Not always, but modern controls can improve comfort and reduce fuel use. If existing controls are outdated or unreliable, upgrading them during installation is usually the most cost-effective time to do it.
What should I do to look after my new oil boiler?
Arrange annual servicing and keep the area around the boiler clear for safe operation and access. It also helps to monitor oil levels and address any unusual noise, smells or loss of pressure promptly.
